Roberts Liardon tells us that the Holy Spirit works the same way with you in the world of the Spirit. When you lean upon the Holy Spirit in your praying, diversities of tongues will come through you and your tone will change as well as your utterances.

Roberts Liardon tells us that the Holy Spirit has expressions too, folks. That’s why monotone praying in tongues usually puts you in a dead end street. It may work for you a little, but it won’t do much for you because you’ve contained it. You need to begin to allow the Spirit of God to manifest diversities of tongues through you privately and at times publicly

I have heard some people say, “Well, tongues is to speak to God with.” (1 Cor 14:2) That’s true, but the Bible says that there are diversities of tongues, which means different kinds of tongues for different things. (1 Cor 12:28) If all you do is limit your tongues to just speaking to God or building yourself up, you’ll never get into the depths of what God has for you.
